Original application med March 11, 1910, Serial No. 548,540. Divided and this application filed December I 19, 1911. Serial No. 866,791. Y

Be it known that l, Jnssr. Pnrnnson, 'a' citizen of the United States of Amerlca,

residing at Lockport, county of Niagara,

State of New York, have invented certain new and useful Improvements in Induratedl iber Articles, of which the following isa specification- My invention relates generally to the production of articles out of indurated fiber and more specifically comprises certain apparatus used in water closets such as seats and tanks, and a special processior making the same in integral pieces out of such fiber.

lhis application is a division ofmy application SerialNo. 548,540, filed March 11, 1910. l

For practical success it iscs'sential that such articles should be formed-of material strongilenough to firmly hold screws driven into t em, and of a character such as will -take a high polish and resist the action of moisture and gases, as well as that of chemical disinfectants used in cleaning. Ordinary indurated fiber will not meet these reuirements, but after a long period of careul experiment I have discovered a process this character can be produced from'such fiber.

In carrying out my process I referably start with a mixture of one-ha f ground wood and one-half 61d newspapers by weight, which. is thoroughly pulped'with water in abeating engine. The pulp is then pumped into dies in sa suitable press and subjected to pressure of from 25 to 30 tons until all but about 30% of water by weight is expressed. The .article so formed is then thoroughly dried in a dry house and pressed dry in a hot press under a total pressure of about 400 tons to thoroughly compact the fibers, after which -it is indur'ated by soaking in a hot mixture of l5% .kidne oil, 45% rosin and 10% parafiin wax and A aking in Thisbaking drives 'ofi all the volatile matter leaving the material a hard, tough, horny mass. -This is sandpapered, painted or varnished, or otherwise finished oil. 1 The kidney oil I find to be the best material for drivin the rosin and wax into the. fibers, and to ave just the rightevapora- Specification of Letters Patent.

tion point to be conveniently driven out of the mass after it has done this work. Kidney oil is the commercial name for the unrran mnonman mean product of the distillation of rosin from which the slight amount of water usually present has not been extracted.

The accompanying drawing shows one form of water closet seat and cover therefor made in accordance with my invention.

The seat 1 is made in one piece, and the cover 2 is hinged to it by hinges 3, 3, fastened to the. parts'by screws,'not shown.

The' article thus produced is capable of taking and maintaining a high polish. It

will not warp, split or splinter under ordi-- I nary use. It will withstand the use of the powerful chemical disinfectants used in cleaning such apparatus, and will hold screws and nails better than natural wood.

The old newspapers used contribute valu- Y able qualities to the finished article both on account of the cg'ndition of the wood fiber composing them, and of the efiect of the printers lnk mixed-with'it. The dry press- .ing in a hot press also contributes much to the ultimate compaetnessand strength of the article.

Having, therefore, described my invention, Iclaim:

1. A composition for use in making water closet seats and" similar articles comprising substantlally equal parts of pulped wood fiber and old newspapers with the printers ink adhering thereto molded and indurated.

2. A composition for use in making water closet seats and similararticles comprising substantially equal parts of pulped wood fiber'and old newspaperswith the printers ink adhering thereto molded and indurated with a mixture of ro sin kidney oil and paraflin wax. a

3. A composition for use in making water closet seats and similar articles composed of pulped wood fiber and old newspapers molded and indurated with a mixture of""" 45% rosin, 45%
